According to another article*, the kid's parents took the phone within a few hours of the teacher sending the kid his grades and exchanging a few more texts. The "hundreds" of texts came AFTER the parents took over the texting.

What if teacher's husband saw some of the parents' texts and decided to mess with a kid he thought was attempting to flirt with his wife? It will be ironic if all these supposedly inappropriate texts were sent between two grown men each pretending to be someone else.
